Comparative analysis of codon usage patterns in chloroplast genomes of ten Epimedium species.

ABSTRACT:

Background

The Phenomenon of codon usage bias exists in the genomes of prokaryotes and eukaryotes. The codon usage pattern is affected by environmental factors, base mutation, gene flow and gene expression level, among which natural selection and mutation pressure are the main factors. The study of codon preference is an effective method to analyze the source of evolutionary driving forces in organisms. Epimedium species are perennial herbs with ornamental and medicinal value distributed worldwide. The chloroplast genome is self-replicating and maternally inherited which is usually used to study species evolution, gene expression and genetic transformation.

Results

The results suggested that chloroplast genomes of Epimedium species preferred to use codons ending with A/U. 17
